tie it known that l. .\l3lt.\.\l t. Moi '1. Jr..a citizen of the l'nited States. residing in Phil adelphia, lennsvlvania. have invented eertain improvements in ,\Iolding-.\laehines. ot' whit-h the following is a speeitiration.

()ne object of my invention is to improve the eonsti'urtion of molding maehiiies in which one part ot' the mold swings on a pivot and another part is adapted to a yielding, vertically movable table.

A further objeet of my invention is to provide means for lo 'kiiig the table in the position to which it is adjusted.

The invention also relates to eertain improvements in the stops for the pattern board.

shaft 5 that it will tend to counterbalance the llask when it is moved from one position to the other. \Vhen the flask is turned back from the position illustrated in Fig. 1, it rests upon the supports 10.

it are handles which are secured to the flask 8 on the side opposite o the brackets T and are used to turn the flask on its pivot 5. he brackets T are vertically adjustable oi; the head t). Eaeh side member f the head has a vertical rib extending into a ver tiral slot in the bracket.

1I-13 are bolts which pass through slots 1;! in the side member of the head. seeiiring the brackets in any position to which tliev are adjusted.

19 is a rarrying t'rame mounted in suitable guides on an extension 14 of the main frame l. The rarrving frame consists of two side members 30 and a eonnecting cross member 51 and tie rods 52. The side members have soekets '3'. at each end and adapted to the soekets are plungers 23, supported by springs it in the soekets. At the Center of each side member is a post 18 which extends to a point directly above a transverse shaft 15 mounted in bearings in the extensi )11 1t of the frame 1. The shaft 15 has two cams 17 on \\'lllt'll rest the posts 18.

It; is a hand lever for turning the shaft to raise and lower the frame 19. On one ol the posts is a lateh '20 arranged to engage a. projertion :21 on the hub of the lever 16 and on the shaft 15, and is for the purpose of lot-king the shaft when the earns 17 are in the elevated position. By lateh. the handle ean be turned in the direction of the arrow so as to lower the frame 19 which carries the bottom board and the lower seetion ot' the flask.

25 is the table which is supported by the plungers 22S and upon which rests the bottom or toliow board 2".

.27 is the drag or lower portion of the flask. and S -is the rope. Mounted between the two seetions h and pattern board :29.

In order to retain the plungers 23 in the position to whi li they are adj'ustl'd. l provide means for ioeking the tour plungers by the ()pfltitltm ot' a, single lev er.

30 are sliding bolts whieh are adii ..'.;d to openings in the s ekets 2'3 and are also adapted to openings in a flange $31. of a plate seeured to the frame it) at the renter. as

27 of the flask is the shown in the inverted plan view, Fig. 3. The ends of the bolts can be forced directly against the plunger-s 23 and thus hold them rigidly in the position to which they are adjusted. The opposite end of each plunger bears against a spring within a flange 31, and a cam 33 has four cam surfaces resting against the springs. The cam is secured to an operating arm 3% projecting at one end of the machine, so that when the operat-ing arm is turned in one direction the bolts are forced against the plungers and when the arm is turned in the opposite direction the cams will release the plungers and will allow them to move.

Mounted on slides 37, Fig. 10, at each side of the machine, are stops 35 and 36 for the pattern board 29. Each slide is slotted, as shownpfor the reception of the lower end of the stop 35 and as this stop is provided with a nut, it can be adjusted in the slot to any position desired. The stop 36 is pivoted at 38 to the end of the slide and has a balance weight 39 so that its normal position will be upright. But, when it is wished to remove the flask, the stop will swing clear of the flask. When the flask is in position both stops will be in line with the pattern board, so that when the table is lowered, the pattern board will rest on the ends of the stops and upon continuing the downward movement of the table the lower flask 27 will be moved away from the pattern board.

53, 53 are levers for operating the sliding plates 54 and 55, which can bemoved so as to project into the opening in the cope 8, retaining the sand after it has been packed in the cope. By moving the levers in thgopposite direction the plates can he retracted so as to be back of the side walls of the cope to allow for the removal of the same from the molded sand. The several plates are slotted at 5-1 for the reception of the pins 54 on the cope and the side plates 54- are recessed at each end, as shown in Fig. 13. to receive projections 55" on the end plate 55 so that when motion is imparted to the side plates 54 the end plates must he moved with them. Each lever 53 is fulcrumed to the rope and one arm of the levers is connected directly to one of the sliding plates 54 and the other arm is indirectly connected to the sliding plates 54 by a bar 56.

While I prefer to employ the particular sand retaining slides and operating means therefor as shown and described, said specific devices are not my invention. and it is manifest that the slides may be constructed and operated in various other ways known to those skilled in the art, for example. as shown in United States Letters Patent No. 1,081,251, issued to me December 9, 1913, for a molding flask.

ad --40 ere centering pins on the lower tionally hold the clamps in the position to which they are adjusted.

The operation of the molding machine is as. follows :In making the mold, the cope 8 is turned back and rests u on the support 10. The pattern board 29 is then placed in position within the drag; the flask 27 being placed in position on the attern board. This drag 27 is then filled with sand and r mmed, after which the bottom board 26 is placed on the flask and the clamps 41 applied. The entire flask is then turned over on to the table 25; the bottom board resting upon the table. The levers 53 are moved so as to project the sand supporting plates into the flask, see Fig. 12, after which the cope 8 is filled with sand and rammed. The clamps 41 are then released and the handle 16 tuned so as to lower the table, and, as the table descends, it carries with it the bottom board 26, the drag 27, and the pattern board 29. The movement of the pattern board 29 is limited as it comes in contact with the ends of the stops 35 and 36, and the drag 27 continues its movement with the table. After the drag has reached the limit of its movement and is supported at the four corners, the table is locked by moving the operating lever 34 which throws the locking bars 30 into frictional contact with the plungers 23. The cope 8 is turned on its pivot clear of the pattern the pattern board 29 and as the pattern board has been freed from the mold within the drag 27, it is carefully raised and removed, after which the cope 8 is again turned over on to the drag 27 and the arm 34 115 is actuated so as to release the plungers 23 and the lever 16 is turned so as to raise the table, bringing the drag 27 in contact with the cope 8. The levers 53, controlling the sand retainin dates are then actuated so 120 as to retract tne lates. When this has been done, the cope 8 is again turned on its pivot, the sand remaining on the sand mold in the drag 27. Then the drag 27 is removed from its sand mold, leaving both sec- 1 5 tions of the mold on the bottom board 26, which is then removed to the pouring floor and the above operation is repeated.
